Abstract: A tire inflation pressure monitoring device includes transmitters for transmitting air pressure signals indicative of air pressures in tires, detected by respective air pressure sensors, and a receiver for generating a warning signal in accordance with the air pressure signals received from the transmitters. The air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal. When the receiver is in an ID registration mode in which the IDs of the transmitters are registered (S12), the transmitters are forced to transmit the air pressure signals, and if the number of the received air pressure signals is equal to a predetermined value, the receiver registers the IDs of the transmitters based on the ID signals included in the received air pressure signals (S20, S26).

Abstract: A base station apparatus for communicating with a specific base station and with a terminal that can move relative to the specific base station. The base station apparatus is provided to be able to move relative to the specific base station, and when the terminal has moved relative to the specific base station, the base station apparatus moves relative to the specific base station substantially in the same direction as the move direction of the terminal.

Abstract: A multicast controller capable of delivering moving image and music data, comprises delivery content announcing means 11 for announcing delivered contents, a reception fee, and a scheduled delivery start time to each of cells A, B; decryption key delivering means 12 for delivering a decryption key for decrypting encrypted data to reception wishing users; user number counting means 13 for counting the number of reception wishing users in each of cells A, B; delivery condition determining means 14 for determining whether or not each cell satisfies a previously set delivery condition; and data delivering means 15 for multicasting the moving image and music data to a cell which satisfies the delivery condition.

Abstract: An ATM-Ethernet portal/concentrator permits a transparent interconnection between Ethernet segments over an ATM network to provide remote connectivity for Ethernet segments. The portal includes an Ethernet controller and an ATM cell processor, both of which receive and transmit data to and from a dual port shared memory under control of a direct memory access controller. A control microprocessor monitors and controls the shifting of data through the dual port memory. In this scheme, original data is written and read directly into and out of the dual port memory to thereby eliminate any requirement for copying of data, to thereby significantly increase the data throughput capability of the portal. In the concentrator embodiment, a plurality of Ethernet controllers, each of which is connected to its own associated Ethernet segment, is multiplexed through the concentrator to an ATM network to thereby provide remote connectivity for each of the Ethernet segments.
